A solid-state method for recycling spent and/or scrap cathode material includes heating a cathode material comprising lithium nickel manganese cobalt oxide in an oxygen-containing atmosphere at a temperature Tfor an effective period of time tto convert the cathode material to a solid precursor, combining the solid precursor with a lithium compound, and heating the solid precursor and the lithium compound in an oxygen-containing atmosphere at a temperature Tfor an effective period of time tto form a product comprising monocrystalline lithium nickel manganese cobalt oxide having a formula LiNiMnMCoO, where M represents one or more dopant metals, x≥0.33, 0.01≤y<0.33, 0≤z≤0.05, and x+y+≤z 1.0.

Direct recycling and converting cathode materials into high-performance single crystal cathode materials

Methods for synthesizing single crystalline Ni-rich cathode materials are disclosed. The Ni-rich cathode material may have a formula LiNiMnMColO, where M represents one or more dopant metals, x≥0.6, 0.01≤y<0.2, 0≤z≤0.05, and x+y+z≤1.0. The methods are cost-effective, and include methods for solid-state, molten-salt, and flash-sintering syntheses.
